Comment (by anonymous):

 One more question:

 Right now, in the attached patch, we have
 {{{
 template<typename T, typename Op>
   void all_reduce(const communicator & comm, const T & in_value,
                   T & out_value, Op op);
 template<typename T, typename Op>
   T all_reduce(const communicator & comm, const T & in_value, Op op);
 template<typename T, typename Op>
   void all_reduce(const communicator & comm, const T * in_values, int n,
                   T * out_values, Op op);
 }}}
 plus
 {{{
 template<typename T, typename Op>
   void all_reduce(const communicator & comm, T * inout_values, int n,
                   Op op);
 }}}
 but we do not have:
 {{{
 template<typename T, typename Op>
   void all_reduce(const communicator & comm, T & in_value, Op op);
 }}}
 that's based on the assumption that there isn't much usage for it and that
 it would cause confusing overload issues.

 I am still trying to find out how to modify the documentation :-)
